How many electrons are lost or gained in silicon?

Answer 1

Silicon has the atomic no. of 14 and has 4 electrons in its outermost shell.

Thus,in order to make bonds it must loose or gain 4 electrons in order to achieve stable configuration but this process requires lot of energy.

Therefore, silicon mostly makes bonds by sharing its electrons.

Answer 2

In silicon, an atom can either gain 4 electrons to achieve a stable electron configuration with 8 valence electrons (like the noble gas argon) or lose 4 electrons to achieve a stable configuration with 4 valence electrons (like the noble gas neon). Silicon typically forms covalent bonds by sharing electrons rather than losing or gaining them.
